All-Solid-State Thin Film μ-Batteries for Microelectronics
1 Introduction. The concept of thin-film batteries or μ-batteries have been proposed for a few decays. [] However it is a long and difficult match since the fabrication of the all-solid-state thin-film μ-batteries (ATFBs) relies on the development of solid electrolytes with reasonably high ionic conductivity and chemical and electrochemical stability.
Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.
